A few days ago I started playing Reus again, My first quick 30 minute game on a medium world to get back into the swing of things worked fine but to my dismay I ran into the same bug (I believe) that made me quit 2 years ago in the second game.

I'm playing with a large world and I'm mixing and matching biomes; forests with some swamp tiles mixed in, swamps with some forest tiles, several small mountains sometimes with a few desert tiles in between, etc. making a really varied world with many different combinations. As this takes a while to set up, with alot of biome repaving along the way, so I start a village or two on one end of the world and work my way outward placing biomes for the rest of the world while I get those first few villages going.

However, after 8-12 minutes while I'm working on the areas for the future villages 5 and 6 the game keeps crashing. I'll be placing a biome down and the game crashes afterwards, I have one save just before it happens that the Forest Giant is about to place a forest and while his animation plays the forest tiles to not appear and the game crashes immediately afterwards. Its not unique to the Forest Giant though, I had the same thing happen with the Swamp and Ocean Giants.

Here's the most recent error report, I've 10 of them already trying to get past that last bit of biome placement.

Happened again today with my Swamp Challenge world, I needed to place some more mountains to get the benefits from some projects but it crashed as I placed them. The Mountain Giant started raising the ground and the game crashed just before the first mountain patch would appear.

As you know, we're super busy with the Renowned Explorers expansion at the moment, but we'd like to pick up some Reus bug fixing again after the expansion is done. We've actually had reports of this issue before, but have never been able to properly track it down. Do you maybe have more information on specific situations where this happens? Maybe save games of just before this happens? It's a crash in the terrain rendering, so screenshots (or specific detailed explanations of which biomes were where at what position etc.) would also be extremely helpful.

I'm also assuming you're running the latest Steam version, is that correct?

I'm well aware that you're all busy with the expansion, I had expected a late response so don't feel bad about it.

Like I said I like to mix and match biomes for more unique worlds and locations, lots of small mountains often with small deserts in between, small patches of forest or swamps in their counterpart, etc. I actually have quite a few saves and while looking for the best ones to sent in I noticed something interesting, it might even be what is causing the problem.

In that Swamp Challenge world that I mentioned in previous post I wanted to place a new small mountain close to a village, it would crash every time I tried to do this. However while testing it out again while sorting through my savefiles I actually made it work, when I placed the mountain further away so the new mountain patches connected to an existing mountain everything was fine. I theorised that there seemed to be a biome limit and the game would crash when crossed, I tested it out in the same world and when I placed a new swamp without connecting it to an existing swamp the game crashed as well.

To fully test it out I made a new large world, made a really big ocean and started placing forests and swamps in a 1 patch chequerboard-like pattern. The game quickly crashed when the number of individual biomes became to high, more than 2/3 of the planet was still uncovered.

Seeing as this is likely caused by some sort of a biome limit, that you guys probably intentionally placed in the game for a good reason, I'm a bit sceptical if you can easily fix it. It starts to sound like this more of a case of "weird things that only I do that breaks the game" to me rather than an actual problem with the game. If it is easily fixable then I would love it ofcourse, but you really don't have to redesign the game's architecture just so I can have all those small mountains and swamp patches in my forests.

I'll still sent in a few safefiles if you want to take a look at them.
